SiT9121 Ultra-Performance Differential Oscillator

SiTime's high-end differential performance for any frequency between 1 MHz to 220 MHz with best-in-class phase jitter of 0.6 ps

Image of SiTime's SiT9121: Ultra Performance Differential Oscillator SiTime's SiT9121 is a highly flexible, ultra-performance, programmable differential oscillator that supports LVPECL and LVDS output signaling types. This differential oscillator covers any frequency between 1 MHz to 220 MHz, with best-in-class RMS phase jitter of 0.6 ps. Unlike quartz or SAW based traditional oscillators, the SiT9121 is available in any combination of voltage (2.5 V to 3.3 V), frequency stability (±10 ppm, ±20 ppm, ±25 ppm, and ±50 ppm), and package (3225, 5032, 7050) options.

Features and Benefits
  • 0.6 ps integrated RMS phase jitter (12 kHz to 20 MHz)
    • Excellent jitter margin for the most stringent applications such as SONET
  • Excellent frequency stability, as low as ±10 ppm
    • Better timing margin that enhances system stability and robustness
  • Extensive programmability
  • Frequency from 1 MHz to 220 MHz
  • Frequency stability from ±10 PPM to ±50 ppm
  • Three industry standard packages
    • 100% drop in replacement for quartz, SAW, and overtone oscillators without any design changes
  • LVPECL and LVDS output signaling types
  • Supply voltage of 2.5 V and 3.3 V
Applications
  • SONET
  • Synchronous Ethernet
  • 10 G Ethernet
  • Fibre Channel
  • PCI Express
  • System clocking
